Question
**Title: Analyzing the Readiness for College-Level Mathematics**

**Introduction:**
A college entrance exam company determined that a score of 24 on the mathematics portion of the exam suggests that a student is ready for college-level mathematics. To achieve this goal, the company recommends that students take a core curriculum of math courses in high school.

**Scenario:**
Suppose a random sample of 250 students who completed this core set of courses results in a mean math score of 24.4 on the college entrance exam with a standard deviation of 3.1. Do these results suggest that students who complete the core curriculum are ready for college-level mathematics? In other words, are they scoring above 24 on the mathematics portion of the exam?

**Task:**
Complete parts (a) through (d) below:

**E.** 
The sample data come from a population that is approximately normal.

**F.** 
None of the requirements are satisfied.

**c) Test Hypotheses Using P-value Approach:**
Use the P-value approach at the α = 0.05 level of significance to test the hypotheses in part (a).

**Identify the test statistic:**
\[ t_0 = \]

(Round to two decimal places as needed.)

**Additional Tools for Assistance:**
- "Help me solve this"
- "View an example"
- "Get more help"

---

**Explanation of Interface Elements:**

1. **Input Field:** 
   - There's an input field for the test statistic \( t_0 \), allowing users to input their calculated value.

2. **Buttons:**
   - **Help me solve this:** Provides step-by-step guidance on how to solve the problem.
   - **View an example:** Offers a similar example with a detailed solution.
   - **Get more help:** Directs to additional resources or tutoring services.

**Note:**
The task involves entering the correct value for \( t_0 \) after performing appropriate statistical tests. The problem is designed to help students understand hypothesis testing, specifically using the P-value approach to infer about population means from sample data.
